It looks like my first comment here didn't save. The bar's movement mechanic in this game was actually rather unique I thought. It adds additional things to consider about your movement, a strategy element of sorts to a platformer. I could see this as a fun puzzle platformer with some additional elements added.
The music went well with it also. I particularly liked the camera focus point being somewhere not in the exact center of the bar so you can feel the up and down movement of your bar "walking."
Good job on the game!
